Shriver says the garden will demonstrate the important role of food and how it gets to the family dinner table. It will also emphasize water conservation, a huge issue in California.
Mrs. Obama last week joined schoolchildren to plant a produce and herb garden on the White House grounds.
Noted California chef Alice Waters had lobbied for a White House garden for more than a decade.
She partnered with San Francisco Mayor Gavin Newsom to plant a vegetable garden outside city hall last summer.
Shriver says Waters will also help build the garden in Sacramento. It will break ground in May.
